GoKawiilStudy details how extinct Haast's eagle killed and fed on giant moa
Researchers published findings in Proceedings of the Royal Society B describing how New Zealand's extinct Haast's eagle, a 15-kilogram raptor with a three-metre wingspan, hunted the massive flightless moa. The international team found the eagle used powerful talons to knock prey over, finished it off with its beak, and then fed on the carcass's insides in a manner similar to a vulture, since it couldn't carry its enormous kill.

The research helps explain a long-standing anatomical puzzle noted by the Natural History Museum's Dr Joanne Cooper, who observes that the eagle's head resembled a vulture's while its feet were distinctly eagle-like. This dual adaptation suggests the species evolved a unique hunting and feeding strategy to cope with prey far larger than itself, offering insight into how extreme ecological pressures can reshape a predator's body plan.
- Haast's eagle, the largest known eagle, lived in New Zealand until roughly 700 years ago.
- It hunted the giant moa by toppling it with its talons and killing it with its beak.
- Unable to carry its prey, it fed on carcasses in place, like a vulture, explaining its mixed anatomy.
